/* NLQ401 Control Codes */
== NLQ401 Control Codes ==
The [[NLQ401]] supports a fraction of the Epson control code set, plus some NLQ401-specific, non-Epson codes. The missing Epson codes include both newer codes, as well as older ones (like custom TAB channelsvertical TABs, which are supported even by very old Epsons from 1981).
Caution: The NLQ401 firmware strips Bit7 of all incoming characters, so one is restricted to use 7bit codes, even if one does own an [[8bit Printer Ports|8bit Printer Port]]. Accordingly, only 7-pin graphics can be used, and some numeric parameters cannot be set to values with bit7=1.
